John 'Ochtery'
Now the VIIIth chief, he was sometimes called on that account 'John Ochtery'. He joined David II with a considerable body of followers, whom he commanded in the third Division of the Scots army at the battle of Halidon Hill on 15th July 1333, when the Scots were defeated by Edward III of England. He continued in the king's service until the English were expelled from the kingdom, and the king firmly settled in the government of Scotland. He married Ellen de Montealto. The Earl of Mar, about 1357, granted a charter to John Cameron, conveying to him and Ellen de Montealto, his wife, in free marriage, certain lands in Strathdon.
